Send a few pics to your sorority sisters

You grab Casey's phone from the nightstand and open the camera app. The lock screen reveals several notifications from worried friends—clearly, Casey hasn't told many people about her pledge week sacrifice. You swipe them away with a smirk.

Positioning yourself in front of the mirror, you strike a pose that showcases Casey's curves in the tight black dress. You snap a few shots, experimenting with angles that Casey herself probably never would have attempted—pouting lips, arched back, one hand lifting the dress hem just high enough to tease.

"Not bad at all," you whisper, scrolling through the results with satisfaction.

You open the Sigma Kappa Theta group chat and type out a message: "Look who's taking her pledge duties seriously. Thanks for the loaner body, Casey!" You attach the sexiest photos and hit send.

Responses flood in immediately.

"OMG Mackenzie! You look so hot in her!" writes Tiffany.

"Better than she ever did," adds Jessica with a laughing emoji.

Brittany, your sorority president, responds with a simple: "Remember the rules, Mack. Nothing permanent."

"Relax, Britt," you type back. "I'm just going to have some fun. Her body will be good as new in a week." You pause, then add wickedly: "Well, maybe a little more experienced."

The last comment earns a flurry of laughing emojis and suggestive comments.

You snap one more photo—this one a close-up of Casey's cleavage in the tight dress—and send it privately to your boyfriend Charlie with the caption: "Surprise for tonight. Don't ask questions, just be at Rooster's at 8. You won't recognize me, but I'll find you."

As you're admiring yourself in the mirror again, Casey's phone buzzes with a text from someone named "Tyler" that simply reads: "Hey, we still on for study group tonight? Haven't heard from you all day."

You roll your eyes. "Sorry, Tyler," you mutter to yourself, deleting the message without responding. "Casey's got better things to do this week than study."

You pose for one final mirror selfie, making sure to capture the sultry look in Casey's green eyes that the pledge herself probably never uses. Looking at the result, you can't help but feel a rush of power. For the next week, this body belongs to you—and you plan to make the most of it.
